(GRANTED UNDER THE AM or MARCH 3, isssylisnmnnnnnnrnir. 30, 1928 3'70 o. c1157)" The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates to a method of securing articles to each other and of introducing and securing the assembly in a container.

The object of the invention is the provision of a novel method whereby a series of units may be connected in a manner to permit the independent removal of each unit without disturbing the assembly. Such a method of securing units finds particular application in a condition where it is desired to retain the balance of the assembly in the bottom of a container and, accordingly, a method of introducing and retaining the assembly in a container constitutes a part of the invention.

The improved methods are illustrated in connection with a round of semi-fixed ammunition.

Fig. 1 is a view in side elevation of an assembled propellent charge secured in a cartridge case;

Fig. 2 is a similar view taken on the line 2-2 of Fig. 1;

Fig. 3 is a view in elevation, showing the preliminary step in introducing the assemso bled charge into the case;

Fig. 4 is a detailed view illustrating the manner of releasably connecting adjoining units.

Referring to the drawings by characters of reference:

There is shown a round of semi-fixed ammunition consisting of a cartridge case A, projectile B and a propellent charge C. The propellent charge is separated into six parts, namely, a base charge a and five increments or Sub-charges, b, a, d, e and f. Each of the charges is contained in a bag 5, having opposite ears 6-6 formed with a single aperture 7. In arranging the unit for assembly, the ears of alternate charges are disposed approximately out of line with'respect to the ears of the intervening charges.

The method employed to connect adjoining charges isidentical in each case and a description of one such connection will be suflicient-"to define the operation. Taking the sub-charge e for illustration, a cord or thread is tied intermediate its length to one of the ears 6, to provide two unequal portions. The short portion 8 is passed down and under the charge cl which is below it and then up through the opposite ear 6 and across the outer face 10 of the charge 6. The long portion 9 of the cord is then tied to the short portion 9 at the center of the face 10, forming a half bow knot 11. A ring 12 is secured to the free end of the portion 9 which is then coiled on the outer face of the charge.

The disconnection of the charge e from the balance of the assembly may then be accomplished by grasping the ring 12 and pulling thereon. This action serves to untie the bow knot 11 and enables the removing force to be applied to the ear to which the long portion 9 is secured. A continued pull then causes the charge 6 to be separated from the charge d, the short portion 8 of the cord slipping out from beneath the charge 03.

The base charge and the sub-charges are connected in the foregoing manner before being introduced into the container. In order that the assembled charge may be readily inserted into the container and secured therein, a pair of hooks or coils 1313 are secured positively in the base 14 of the container. A pair of cords 15-15 are then each looped over one of the coils, the free ends extending clear of the mouth of the container. One end of each cord, after being passed through one of the ears 6 on the base charge, is tied by means of a slip knot 16 to its corresponding end. By pulling on the unknotted end of each of the cords 15, the assembled charge is drawn to the bottom of the container and the tightening of the slip knot will serve to A method of secfi'liingi units": for individual:

removal, which consists in securing a cord itslength to one unit, passing 7 one portion of the cord around an adjoining unit and up over the outer face of the unit to which it is secured, and rele'asably securing -the other; portion of the cord to the. circumscribing portion.
